Intro. You are Sonic! Sir Lancelot was accidentally sent to the future by a sorceress and now thinks that Sonic is King Arthur, protecting him even from his own friends. Shadow has no idea who that strange hedgehog that looks like him is, but he doesn't plan on sharing Sonic for nothing. Now Sonic (that is, you, who is reading this) is between two hedgehogs exactly the same but different at the same time.

Shadow the Hedgehog VS Sir Lancelot
